However, in brief, I think the connecting of 'God' and 'Being' is one of these things for which there seems to be a natural impulse in human thinking but it can also lead to confusions. Religious believers mostly want to see God as the epitome of what is most really real and in some non-theistic contexts, people talk simply of 'Isness'.

I'm not sure if Cupitt himself still uses this term, but it's useful in suggesting that, actually, there are more choices than the choice between nihilism and faith. In fact, the issue may not be faith as such but the fact that for millennia, Christianity has buttressed itself with a particular kind of metaphysics that has now seemingly reached the end of its life-span. But perhaps Buddhist metaphysics could provide an alternative here - or, at least, offer a direction of travel.

Of course, it's always difficult to disentangle fact from fiction in relation to, e.g., the singularity project. Many scientists I know are dismissive of transhumanist claims, BUT the last 100 years has surely taught us never to underestimate the pace and scope of scientific progress. However, even if much of this turns out to be science-fiction, it also reveals a way of thinking about human life that I find deeply troubling.

It's strange that in an age when we pride ourselves on our independence of thought we meekly submit without further question to the declaration of a clearly unbalanced nineteenth century philosopher that God is dead! That's cheeky, of course - and one rarely comes away from reading Nietzsche without learning something new and significant. He's certainly FAR more unsettling for faith than any contemporary atheist I know of.

Positively, he [Heidegger] shows that the prospect of death doesn't of itself destroy all possibilities of meaning but calls instead for these to be relocated from fantasies about a future post-mortem life. However, I don't think he does enough in this work to show that this relocation has - I believe - a primarily ethical character (in Levinas's sense of 'ethical').

At a theoretical level, I think a naturalist approach to religion is just asking questions I'm not interested in. They're perfectly legitimate in their own terms, but they don't address the actual experience of how one or other aspect of religion becomes existentially meaningful to us in our actual lives. The fact that we ourselves are the subject of investigation makes all the difference.

Ultimately, we live in the face of an irresolvable mystery about our origin and, for that matter, about our end. And what Schleiermacher would have us do is (a) acknowledge that this is the case and (b) accept it as something positive, a point of departure for a life of trusting joy.
